Do I need a factory audit to apply for the Coal Safety/Miner Safety Mark? -- Shenzhen ZhongNuo Inspection Technology Co., Ltd.
Necessity. Unlike obtaining the explosion-proof certificate, stricter control is applied to the mining markings.
Application for Coal Safety and Mine Safety Certification requires a factory inspection of the applicant company.

Coal Mine Safety Sign Certification is a mandatory certification implemented by the Coal Mine Safety Sign Office for products used underground in mines. Any product listed in the Coal Mine Product Safety Certification Catalog must obtain a certification certificate.
Products with Coal Safety/Mineral Safety certification can affix the MA/KA mark. Individuals and entities are prohibited from selling, purchasing, or using mineral products included in the safety mark management catalog that have not obtained the safety mark.
The manufacturer of the product must undergo several steps to obtain a safety mark, including filling out an application form, preliminary review and qualification registration, evaluation, and certification.

What are the requirements for obtaining coal safety certification and mine safety certification?
Coal Safety Certification and Mine Safety Certification are mandatory certifications for mining products and equipment.
Coal safety certification is for equipment used in coal mines, while mine safety certification is for non-coal mine equipment. Both are applied for, reviewed, and certified by the Safety Standard Center.
Certificates are valid for 5 years and require annual supervision and evaluation.
To apply for coal safety and mine safety certifications, both product testing and factory audits are required. Applicants must possess design and development capabilities, provide complete product design drawings, and own a production factory.
Some products can also apply for Coal Safety and Mine Safety certifications through the OEM method.
